The plant wants to make fruit. If you want the fruit (I wouldn't ) then leave them on. If you want flowers (I would) cut them off.

Along the scraggly ends there are probably leaf buds, which will fill out in time, giving you long branches. I would cut them off, back to some good looking leaf joints. The plant will probably branch at that cut, giving you two or three branches, all of which will give flowers. Overall the plant will look better if it is trimmed back. It will flower when it is ready, not much to do if you don't want it to flower. Sometimes people try to shape their plants, when flowers come there is not much else to do but let them bloom.
